the materials for the shoes during the mak-l ing thereof.

lt is desirable in the manufacture of Goodyear welt shoes'to support the materials for the shoes throughout the making and finishing operations. By this practice the last is subjected to a heavy crushing pressure during the heeling operation. Notwithstanding the fact that numerous attempts have been made to strengthen the lasts to withstand the strains of the heeling operation this heavy pressure has a destructive action upon the last heelparts. llt has been proposed to separate the heelpart from the forepart while leaving the latter in position in the shoe so that the heel seat of the shoe could be placed over the post of a heeling machine and the heeling operation performed without danger of injury to the last. Such lasts are lso jointed that the heelpart of the last may be swung on the forepart to extend and collapse the last and the heelpart separated from the forepart when desired. lin order to Separate the heelparts from the foreparts in these lasts it is necessary to move the heelpart rearwardly of the shoe resulting in the difficult removal of the heelpart from the shoe or injury to the counter.

@ne of the objects of the present invention is to produce a last havlng a heelpart which may be readily separated from the forepart and removed from the shoe without danger of injury to the counter.

To the accomplishment of this object a feature of the invention contemplates the provision, in a last provided with a forepart and a heelpart, of a connection between the fore and heel parts permitting the pivotal movement of the heelpart upon the forepart to collapse and extend the last and the separation of the heelpart from the forepart by a continuation of the collapsing pivotal movement of the heelpart beyond collapsed position. 'llhis construction obviates the necessity of moving the heelpart rearwardly of the shoe during the separating movement.

ln the broader aspects of the invention the connection between the fore and heel parts may be formed in any suitable manner 4 found desirable or expedient. lin the preferred form of the invention the connection between the fore and heel parts takes the form of a cooperating pin and slot connection and this manner of connectingthe fore and heel parts to permit the pivotal movement of the heelpart upon the forepart to collapse and extend the last and the separation of the heelpart from the forepartby a continuation of the collapsing pivotal movement of the heelpart beyond collapsed position forms an additional feature of the invention.

A further object of the present invention is to support the materials for a shoe during the making thereof so that the heeling operation may be performed while .the shoe contains the last without injury thereto.

With this object in view a feature of the present invention contemplates the provision of a device for supporting the materials of a shoe during the making thereof consisting of a last provided with a projecting cylindrical socket and a post provided with a pin and a Vwall to enter and receive the socket respectively.

Broadly considered the last may be provided with a socket in any suitable manner. ln the preferred form of the invention the heelpart of the last consists of a heel shaped plate provided with a nail clenching surface upon one face and a cylindrical socket projecting from the other face. In order that the counter of the shoe may be properly supported during the making and linishing operations the heel shaped plate is provided with a counter shaped wa'll rising from the peripheral edge of the plate, and the pin socket is formed upon-'the plate within this wall. This construction forms another feature of the present invention.

lIn the accompanying drawings illustrating the invention in the best form now known to the inventor, Figure 1 is an inverted elevation, partly in section, of the last, forming part ofthe improved device for supporting the materials for a shoe during the making thereof; Fig. 2 is an inverted side elevation thereof showing the heel part in position to be detached from the last, and Fig. 3 is a perspective of a post employed with the last to support the materials of the shoe during the heeling operation.

Referring now to the form of the invention illustrated in the drawings, a wooden forepart 1 is provided with a sloping vertical wall 2. This wall is bored to receive a steel block 3 which is secured to the forepart s0 that its outer surface is flush with the wall 2. The block carries a transverse pin 4 and a tube 5 is arranged in a bore eX- tending longitudinally of the last, and serves to strengthen the forepart weakened by the removal of the wood.

The heelpart of the last is made of steel suitably pressed into the form illustrated in the drawings. As shown the heelpart consists of a heel-shaped plate 6 provided with a nail clenching surface 7 upon its lower face and with a cylindrical socket 8 projecting from its upper face. In order to support the rear of the shoe a counter shaped wall 9 rises from the peripheral edge of the plate 6.

The plate 6 carries an arm 10 which extends beyond the straight edge of the plate so that its end may enter an opening 11 in the block 3. The end of the arm 10 is formed as a slot 12 which hooks u nder the pin 4 so that the heelpart may swlng upon the forepart to extend and collapse the last. In order to lock the last extended the end of the arm 10 is provided with a groove 13 which, when the last is extended, is engaged by the head of a pin 14 loosely mounted in the tube 5. In order that the pin may auto* matically engage the groove as soon as the last reaches extended position and be automatically disengaged therefrom when pressure is applied to the heelpart to collapse the last a spring 15 is coiled around the pin 14 and interposed between the head of the pin and a screw 16 threaded into the end of the tube 5. l/Vhen the last is moved into collapsed position the lspring pressed pin 14 automatically engages the lower edge of the slot 12 (see Fig. 2) and locks the upright collapsed heel part from returning to eX- tended position under the influence of gravity. When it is desired to separate the heelpart from the forepart a continuation of the pivotal collapsing movement of the heelpart beyond collapsed position causes the arm 4 to swing out of engagement with the pin 4, thus permitting the heelpart to be removed without rearward movement of the heelpart to-ward the counter of the shoe. The provision of a pressed steel heelpart, however, permits the heeling operation to be performed with the heelpart in the shoe without injury to the last. In order to support the heelpart firmly during the heeling operation the socket 8 receives a pin 17 formed upon a post 18, and the socket is in turn received within a wall 19 formed upon the post and spaced from the pin. The end of the wall 19 bears against the heel part around the base of the socket 8 and supports the heel plate 6 against the thrust of the heeling machine. The end of the pin 17 also bears against the heel plate 6 and supports it, while the bottom of the slot 20 bears against and supports the rib 10. In order to prevent the socket from turning upon the pin 17 the wall 19 is provided with a slot 20 which receives the arm 10. In order that the steel heelpart may properly hold the insole and the heelpart of the upper a wooden tack receiving block 21 is inserted in the back of the wall 9 and also in the nail clenching surface 7.

The nature and scope ofthe present invention having been indicated and one form having been specifically described, what is claimed as new is v 1. A device for supporting the materials for a shoe during the making thereof consisting of a last provided with a projecting cylindrical socket and a post provided with a pin and a wall to enter and receive the socket respectively, substantially as described.
